This stock trans. is from a 1987 Monte Carlo , code CRF, about 100K on it, ran well. I believe these models shift at 4800-5000 rpm. Its been setting in dry storage about 1yr.1/2, fluid looks good, comes with dip stick tube & TV cable works very smooth, theres no convertor or wire plug for total lock-up. NOT greasy or grimy looking. Can use B&M or TCI lock-up kits. The gentleman built a 10 sec, motor and did not want to spend the money on a 200-4R and instead did a 400 turbo. I was going to use it with a buick 350 motor in my 61 buick Lesabre, now I have to channel some money in to a work truck. I do not want to ship this right now, would like to sell it local. I'm 40 mins from Ohio line if that helps anybody in ohio. FOR SALE: $280.00
